Things to watch for
- US and UK gallons are different. 1 US gal = 3.785 L; 1 UK (imperial) gal = 4.546 L. Recipes from the UK will not work with US cups.
- Volume scales as the cube of length: doubling a container's dimensions multiplies volume by 8, not 2.
- For viscous or compressible fluids, volume changes with temperature and pressure. Specify conditions for precise work.
What is a US tablespoon?
One US tablespoon equals exactly 0.5 US fluid ounces or about 14.79 milliliters. American cooking recipes.
What is a milliliter?
One milliliter equals exactly one cubic centimeter (1 ml = 1 cm³) or one-thousandth of a liter. Liquid medicine dosing, recipe ingredients, and laboratory measurement.

Frequently asked questions
How do I convert tbsp (US) to ml?
Apply the formula tbsp (US) → ml shown above, or just type your value into the converter at the top of this page. The result updates instantly.
Which is bigger, tbsp (US) or ml?
This depends on the conversion ratio in the formula. If the factor multiplied by your value gives a larger number, then ml is the smaller unit (so it takes more of them to express the same quantity). If the result is smaller, then ml is the larger unit.
When would I use tbsp (US) versus ml?
Both units measure volume, so the choice depends on context. Us tablespoon is typically used for cooking, beverages, fuel, and industrial fluid handling; milliliter similarly. Most professional fields standardize on one or the other based on regional conventions or technical tradition.
How precise is this tbsp (US) to ml conversion?
The conversion factor shown is the internationally defined exact value (or the best-published approximation if the relationship is irrational, like degrees-to-radians). The live converter on this page uses double-precision floating-point math, accurate to about 15 significant digits — far beyond any practical engineering need.
Is the conversion ratio exact, or an approximation?
Most unit conversions between SI metric units, and between SI and US customary units, have been formally defined as exact values since the 1959 international yard-pound agreement and subsequent SI redefinitions. Exceptions are unit pairs that involve irrational numbers (radians, e.g.) or empirical conversions (like food calories, which depend on temperature). When in doubt, consult the formula at the top of this page.
